Abstract (en)
The invention relates to a strapping head and a strapping machine with said head. The strapping head comprises a first tamper, a second tamper and a third tamper involved in the strap casting, recovery, tightening, welding and cutting operations, each of the tampers being provided with a respective work surface oriented towards one of the faces of the object to be strapped, each of the tampers being susceptible to being shifted in a direction perpendicular to their work surfaces, essentially parallel to one another, between a forward movement end position and a backward movement end position with respect to the object to be strapped and the strap that will wrap it, by means of respective electro-pneumatic drives. The mentioned electro-pneumatic drives of each tamper are pneumatic cylinders, preferably having an elliptical section.
